When maintaining or repairing your Graco spray equipment, it’s essential to have a comprehensive parts breakdown and all the right supplies to keep your sprayer working at peak performance. Whether you’re searching for Graco Magnum X5 parts, Graco pump repair kits, Graco sprayer accessories, or just stock up on Graco spray tips, this detailed guide will help you navigate the Graco Mark VII Max parts list like a pro.

Overview of Mark VII Max Series Parts

The Graco Mark VII Max Series, along with the closely related Mark X Max, is built for rugged performance, offering up to 3,300 psi for demanding coatings. SprayersAndParts divides the breakdown into six core categories:

1. Sprayer Parts List – All-in-one view of pressures, seals, and structural components.

2. Control Box & Circuit Board – Electrical components that govern the unit's operation.

3. Pump Breakdown (PN 287946) – The heart of your equipment.

4. Filter Assembly – Maintains fluid purity and protects the pump and spray tips.

5. Hose Reel & Guns – Spray delivery system.

6. Bearing Housing – Structural support and durability. 

1. Pump System Components

The pump breakdown (Part No. 287946) includes piston rods, seals, check valves, pump housings, and manifold filters. These are essential for maintaining consistent pressure and flow—common parts you'll find in Graco pump repair kits. A typical rebuild involves:

• Piston rod assemblies

• Check valve assemblies

• Pump housing

• Manifold filters 

Pro Tip: Rebuild the pump annually or after heavy use to avoid system failure.

2. Control Box & Circuit Board

The control box breakdown covers everything that makes your sprayer “smart”:

• Control panels and potentiometers

• Rocker and reed switches

• Circuit boards (Mark VII/Mark X)

• Knobs, wiring harnesses, power cords

• Display and cord kits including repair accessories

These are core Graco sprayer accessories, essential when troubleshooting electrical issues like power failures, inaccurate pressure readings, or non-responsive controls.

3. Filter Assembly

The filter section safeguards your fluid and protects your Graco spray tips. It typically includes:

• Fluid filters (30 mesh, 60, 100, 200 mesh)

• Cap/filter base assemblies

• Transducer and O‑ring packs

• Valve seats, diffusion tubes, drain/prime valves 

Maintenance tip: Replace filters every 50 hours or sooner to prevent clogs and wear.

4. Hose Reel & Spray Gun Components

A reliable hose and gun setup ensures optimal delivery at the job site. Key items include:

• Coupled hoses (½″) and whip hoses

• Spray guns (e.g. inline texture gun)

• Swivel fittings and hose reel parts

• Hose reels and pivot mounts

Pair them with Graco Magnum X5 parts—though for compatibility, check dimensions and fittings before ordering.

5. Bearing Housing & Cart Assembly

This section includes:

• Frame, cart parts, legs, pneumatic wheels

• Bearing housings and brackets

• Motor shields and protective covers 

Vital for maintaining mobility, protection, and structural integrity of your unit.

6. Electrical Motor & Mechanical Drive Components

Includes:

• Electric motors with fan assemblies

• Drive gears, pistons, and connecting rods

• Switches and strainers

• O‑rings, seals, and check‑valve repair kits

These components are frequent items in Graco pump repair kits and critical for maintaining consistent output.

Signs You Need Replacement Parts

Keep an eye out for these symptoms indicating potential part issues:

• Uneven pressure or inconsistent spray → Failed seals, pistons, valves, or spray tips.

• Fluid leaking or cracked housings → Replace O‑rings, housings, or pump bodies.

• Grinding noises or motor vibrations → Inspect bearings, motor components, or electrical parts.

Combining symptoms across system components will guide you toward specific replacements or full rebuild kits.

Frequently Asked Questions

Which kit is right for my Mark VII Max pump?

Typically, pump repair kits include seals, O‑rings, check valves, and pistons. Compare the kit with the parts list (e.g. PN 287946) to ensure everything you need is included.

Are control board parts interchangeable with Mark X Max?

Many electrical components like switches, cords, potentiometers, and circuit boards are shared between Mark VII Max and Mark X systems—check part numbers or wiring labels to confirm.

How often should I replace spray tips?

For consistent coatings, replace Graco spray tips every 100–200 gallons or sooner if wear appears. Worn tips increase pressure requirement and deliver uneven fan patterns.

2. Locate the relevant exploded diagram and Graco parts list category.

3. Order single components or go for a Graco pump repair kit for full restoration.

4. Don’t forget Graco sprayer accessories—gloves, tip cleaners, filters, pressure gauge replacements.
